HYPOCRYPTURELLUS CONICEPS IDONEUS, new subspecies 
FIGURE 29, a 
Types.—Male and female, adults, from Crypturellus idoneus, col- 
lected by the author at Carraipia, La Guajira, Colombia, May 30, 
1941; in U. S. National Museum. 
Diagnosis.—Closely related to H. c. boucardi of Mexico, from which 
it differs as follows: Both sexes are slightly smaller in practically all 
dimensions (see table of measurements); in the female the head is 
almost the same length at the occiput but considerably shorter at the 
temples, while the width at the temples is but slightly less, and at the 
frons proportionately narrower (0.347 against 0.38). The propor- 
tions of the head in the male are practically the same, only slightly 
smaller. 
The genital armature is of the same general style, the chief differ- 
ence being in the endomeral plate. The paramers are some shorter, 
but slenderer distally and differently shaped basally; the basal plate 
1s narrower at its junction with the paramers and is more deeply con- 
stricted just forward of that point. The endomeral plate is very dif- 
ferently shaped in every way, both basally and distally (see figs.) 
and resembles in several features that of H. ¢. undulatus Carriker. 
HYPOCRYPTURELLUS CONICEPS BOUCARDI, new subspecies 
FIGURE 29, b 
Types.—Male and female, adults, from Crypturellus 6b. boucardi, 
collected by the author on Cerro Tuxtla, Veracruz, Mexico, March 28, 
1940; in U. S. National Museum. 
Diagnosis—This race of coniceps has the genital armature more 
nearly resembling that of H. c. undulatus (from Crypturellus u. un- 
dulatus) than of any other of the known races, from which it differs 
in larger size, with longer, slenderer, and more curving paramers and 
slightly longer endomeral plate, which is also of slightly different 
shape. Measurements of the genital armature in the two races are as. 
follows:
